Definitions
- the invention relates to a coating for pistons, in particular a coating for the piston skirt of an internal combustion engine.
- Coatings for the piston skirt should have a high wear resistance with at the same time a low friction coefficient.
- the passage through the coating in the load-bearing areas of the piston skirt should be avoided.
- This lubricant composition comprises a mixture of graphite, MoS 2 and PTFE in a matrix of a polyamide-imide resin (PAI resin).
- PAI resin polyamide-imide resin
- the EP 1 469 050 A1 describes a coating composition for pistons obtained by mixing uncured polyamide-imide (PAI) with a solid lubricant such as PTFE, titanium oxide powder and a silane coupling agent.
- PAI uncured polyamide-imide
- a solid lubricant such as PTFE, titanium oxide powder and a silane coupling agent.
- the DE 10 2005 026 664 A1 also describes a coating for a piston based on a PAI paint.
- This coating is PTFE-free and contains 5-15% by weight of zinc sulfide, 5-15% by weight of graphite or MoS 2 and 5-15% by weight of TiO 2. Both zinc sulfide and TiO 2 are in the form of fine particles used with a particle size of ⁇ 0.7 microns.
- the DE 43 43 439 A1 describes a reciprocating piston assembly having a piston with a relief-shaped piston skirt with webs, which are coated with a solid lubricant made of graphite, MoS 2 , BN in an epoxy resin.
- the EP 0 976 795 A2 describes a corrosion-protecting lubricant for hinges or the like which contains as a lubricant a mixture of phenol resin, epoxy resin, polyvinyl butyral resin and polyolefin wax.
- the coating further contains aluminum, zinc particles or a metal phosphate as a corrosion inhibitor and a solvent.
- the DE 103 29 228 A1 describes a polymer composite material for plain bearings with a polymer matrix, which can consist of epoxy resin or PEEK, for example.
- a filler and nanoscale particles are embedded.
- Aramid fibers, glass fibers, carbon fibers, glass beads, PTFE, graphite and Silkone can be used as filler material.
- the nanoscale particles can be formed by TiO 2 , Al 2 O 3 , MgO, ZeO 2 , SiC, Si 3 N 4 , BN, glasses and metallic hard materials.
- the invention has for its object to provide a coating composition for a piston, which has an improved wear resistance and minimizes friction losses in the engine.
- the composition used comprises a thermosetting phenolic resin.
- Thermally curable phenolic resins so-called resoles, in contrast to the novolacs, can crosslink via hydroxyl groups. Preference is given to using phenolic resins having an average molecular weight of 500-1500 g / mol.
- the composition used further comprises an epoxy resin.
- epoxy resins generally improves the adhesion of the layers to metallic surfaces and their flexibility.
- Epoxy resins based on bisphenol A having a molecular weight of 2000-4000 g / mol and an epoxy equivalent of> 700 g / mol are preferably used for this purpose.
- these resins are preferably used as a solution in a solvent.
- the choice of solvent depends essentially on the type of paint application and has no influence on the properties of the cured coating.
- the coating of pistons is often carried out by screen printing.
- solvents with a high boiling point are preferred for this application.
- Suitable solvents are e.g. Butylglycol acetate, ethyl glycol acetate, dipropylene glycol, dipropylene glycol butyl ether, butoxyethanol.
- the phenolic resin and optionally the epoxy resin may alternatively be used as a water-dilutable dispersion become.
- graphite As solid lubricants graphite, MoS 2 , WS 2 , BN and / or PTFE are added to the composition.
- the skilled worker can be used as a solid lubricant familiar qualities. Preference is given to using graphite having an average particle size of 1-100 ⁇ m, particularly preferably 5-50 ⁇ m.
- Molybdenum disulfide is preferably used with an average particle size of 0.1-50 ⁇ m, particularly preferably 0.1-10 ⁇ m.
- Boron nitride in the hexagonal modification is preferably used with an average particle size in the range of 1-100 ⁇ m, particularly preferably in the range of 1-20 ⁇ m.
- Polytetrafluoroethylene (PTFE) Raw materials are preferably used with an average particle size of 1-100 ⁇ m, particularly preferably 1-20 ⁇ m.
- MoS 2 When MoS 2 is used as the solid lubricant, it is preferably used in an amount of 10-20% by weight based on the total composition.
- the grain size of the o.g. Solid lubricants can be measured by means of scattered light methods in a manner known to those skilled in the art.
- the composition used contains carbon fibers. Preference is given to carbon fibers having an average fiber thickness ⁇ 100 ⁇ m, preferably from 1 to 10 ⁇ m, and an average fiber length ⁇ 1000 ⁇ m, preferably from 10 to 500 ⁇ m.
- the composition used may also contain so-called carbon nanofibers whose average fiber thickness, in contrast to conventional carbon fibers, is less than 1 ⁇ m, preferably in the range of 10-500 nm.
- the thickness and length of conventional carbon fibers are determined with a light microscope. For carbon nanofibers, these can be determined by scanning electron microscopy.
- composition may also contain additives and auxiliaries, such as, for example, leveling additives, defoamers, wetting agents, dispersing aids or also rheology additives.
- auxiliaries such as, for example, leveling additives, defoamers, wetting agents, dispersing aids or also rheology additives.
- the amount of resins refers to the solids content.
- the amount of additives and auxiliaries refers to the delivery form.
- the tribological properties of the layers were investigated with a Cameron Plint TE-77 Tribotester (Vibration Abrasion Test).
- a Cameron Plint TE-77 Tribotester Vehicle Abrasion Test
- aluminum samples were coated with the coating formulations according to the invention and the coefficients of friction of the layers were measured in a pairing with cast iron as counter-body.
- the measurements were carried out under a load of 150N and at an oscillation frequency of 25Hz in the non-oiled state.
